TO ALL WHOM'IIMAICONCERN; I p

Be it known that I, Pnrnn SnnLLE-Nn'oc'ic, ofM-iddletown, in Butler county, Ohio, haveirrven ted a new and useful Improvementin Visesfandl doflhcreby declare that the following is a full and exact deseription thereof, reference being had to the aceompauying drawings, and to the letters of reference marked thereon? I Figured isa perspectiveview of my'improved vise. w v I I i "Figure 2 represents the'hand-lever, with 'its slotland detent. ;-To e'ntlhle others to construct and use my invention, I will proceed to describe it,'w ith reference to the drawings, which are made a part of this specificatidnL- I v The oblong motal frameA serves as a support'and; guide for the' jawsB, whichsembrace the siderails of 7 frame A,"by'shouldersb b, above and below the frame A. The right and-left screw-bolt C is journalled in the ends of the frame A, and one of itsjourna'ls'extendsthroughthe e'ndof'frame A, to receive a scalloped wheel, D, and theend of slotted lever sereiwbo'ltfl passes through that part of each of the jaws 13 between the two rails of frame 'A,'an d these-jaws arc acted upon simultaneously, to cause them to approach or recede from veach other by the. revolutions of screw 0, whiclrworlcs in thefemale screwsin the jaws. The scalloped wheel D is keyed I tot'he journal of screw 0, and the journal extendseitt;passing' through the slot of'-lever-E, whieh is held thereon by'n ut The strong metal frame A serves as a way in which the jaws. 13 travel. The jaws being provided with grooves, formed by shoulders 25 6, (those below the frame not-seen in the drawings) embrace the side frame-piec cs A, and cause the jaws to-movo s quarely'towards each'other or from each other; and when the clamping-faces take hold of any formed piece of metal .or other material, there can be no lateral .strain or twisting, as inthe'eommon vise. The frame A may be permanently secured to a. bench, such as machinists or artisans:generallyasef "lheprojecting portion'of the journal of'scrcw Gis cylindrical, so that the orifice M, inlever E, will freely revolve thereon. The rletent F, projecting from 'lcverE, overthe periphery of scalloped wheel I), is of nearly'the same diameter as 'thesegmental scallops in the wheel, and will freely enter either of these curved depressions in the periphery of wheel Jts'the wheel D is keyedto the journal of the screw C, itwill neeessarily'revolve with it, and the lever, E is frce to be moved around the journal when the detent F is not occupying one of the scallopsof wheel D. Now, as the lever is capableof being adjust-ed upon-the end of screw-bolt C so as to throw thedetent F into or out of the scallops of wheel D, it wilI'be understood that lever E'may be brought into action, to open or close the jaws of the vise, at any desired position in relation to the w hench, or to the person using the vise. This capability will often render the attendant superior advantage in i leverage, He may with the greatest facility slide theilever upon-the journal of" the screw 0, so as to throw 1 the detcntr out of connection with the wheel D, and change the position of the lever so as to exert more power thereon, and insert the detent in another of the scallops of the "wheel. This wheel maybe provided with as" many scallops or notches for the detont as maybe-found advantageous, and the lever may be provided with a. M light-flexible spring, to retain the detent in the notch or scallop. of the wheel until it is necessary to change the detent to another position. It will be readily seen that the use of the right-and-ieft screw 0 will cause the jaws to openand close with double the speed of the common vise, and by one half the number of revolutions of the hand-.lever'E. I 1

Having fully described my invention and its operation, what; claim as new, and desire to secure by Letters Patent, is'- j 1. The right-and-lelt screw C, in combination with frame A and jaws B, constructed, arranged, and operating in the manner and/for the purpose substautia-lly'as described. I p

2. The'lever E, with its slot M and detent F, in combination with scalloped wheel D and screw C, for operatingthe jaws B in the manner and for the purpose described. i V I In testimony whereof, I hereunto set my hand, this 21st day of June, 1866.
